Examination of pharyngeal teeth causes extensive damage to a...
Tag retention and survival of juvenile bighead carp implanted with an acoustic tag at three temperatures Tag retention and survival of juvenile bighead carp implanted with an acoustic tag at three temperatures
Bighead carp Hypophthalmichthys nobilis and silver carp H. molitrix (together, the bigheaded carps) are considered among the most problematic of invasive fishes in North. Movement and behavior of bigheaded carps has been studied through telemetry methods although the majority of work has occurred on large, adult fish; smaller, juvenile bigheaded carps have not yet been evaluated...
Survival and drifting patterns of grass carp eggs and larvae in response to interactions with flow and sediment in a laboratory flume Survival and drifting patterns of grass carp eggs and larvae in response to interactions with flow and sediment in a laboratory flume
A series of laboratory experiments were conducted to better understand the behavior of grass carp eggs and larvae in moving water in order to develop and implement new strategies for control and prediction of their dispersal and drift at early life stages. Settling velocity and density of a representative sample of eggs were estimated, and three trials of flume experiments with different...

We measured ontogenetic changes in routine and maximum swimming speeds of bighead, grass, and silver carp larvae. Daily measurements of routine swimming speed were taken for two weeks post-hatch using a still camera and the LARVEL program, a custom image-analysis software. Larval swimming speed was calculated using larval locations in subsequent image frames and time between images...

Assessing the efficacy of oblique bubble screens for control of aquatic invasive species Assessing the efficacy of oblique bubble screens for control of aquatic invasive species
Non-physical barriers, such as bubble screens (or curtains), are promising low-impact strategies to deter the spread of Aquatic Invasive Species (AIS) in streams. Bubble screens have been successfully implemented to redirect and/or deter adult fish and to capture plastics in some rivers, but their efficacy on invasive fish at multiple life stages (eggs, larvae, and adult fish) is not yet...

Ingested toxicity of antimycin A to grass carp Ctenopharyngodon idella and black carp Mylopharyngodon piceus in two carriers Ingested toxicity of antimycin A to grass carp Ctenopharyngodon idella and black carp Mylopharyngodon piceus in two carriers
Toxic baits are a potential control mechanism for nuisance carps, but rotenone-based baits for grass carp Ctenopharyngodon idella have been ineffective. Failures have been attributed to the palatability of rotenone because innocuous training pellets are readily consumed prior to provision of piscicide baits. Several studies suggest antimycin A, a common alternative piscicide, typically...

Evaluations of Lagrangian egg drift models: From a laboratory flume to large channelized rivers Evaluations of Lagrangian egg drift models: From a laboratory flume to large channelized rivers
To help better interpret computational models in predicting drift of carp eggs in rivers, we present a series of model assessments for the longitudinal egg dispersion. Two three-dimensional Lagrangian particle tracking models, SDrift and FluEgg, are evaluated in a series of channels with increasing complexity. The model evaluation demonstrates that both models are able to accommodate...

Establishment of invasive Black Carp (Mylopharyngodon piceus) in the Mississippi River basin: Identifying sources and year classes contributing to recruitment Establishment of invasive Black Carp (Mylopharyngodon piceus) in the Mississippi River basin: Identifying sources and year classes contributing to recruitment
Black Carp (Mylopharyngodon piceus) was imported to the USA to control aquaculture pond snails. This species has escaped captivity and occurs in parts of the Mississippi River, several tributaries, and floodplain lakes, which is concerning due to potential competition with native fishes and predation on native mussels, many of which are imperiled. However, Black Carp captures have...

A three-dimensional Lagrangian particle tracking model for predicting transport of eggs of rheophilic-spawning carps in turbulent rivers A three-dimensional Lagrangian particle tracking model for predicting transport of eggs of rheophilic-spawning carps in turbulent rivers
Grass carp, bighead carp, and silver carp spawn in flowing water. Their eggs, and then larvae, develop while drifting. Hydraulic conditions and water temperature control spawning locations, egg survival, and the downstream distance traveled before the hatched larvae can swim for low velocity nursery habitats. Existing egg drift models simulate the fluvial transport of carp eggs but have

Winter habitat selection and efficacy of telemetry to aid Grass Carp removal efforts in a large reservoir Winter habitat selection and efficacy of telemetry to aid Grass Carp removal efforts in a large reservoir
Grass Carp Ctenopharyngodon idella were introduced in North America to control aquatic vegetation in small, closed systems. However, when they escape into larger systems in which they can reproduce, they have the potential to cause significant declines and alterations in aquatic vegetation communities. These alterations can in turn affect native species that are dependent on aquatic...

Identifying turbulence features hindering swimming capabilities of grass carp larvae (Ctenopharyngodon idella) through submerged vegetation Identifying turbulence features hindering swimming capabilities of grass carp larvae (Ctenopharyngodon idella) through submerged vegetation
Aquatic vegetation can provide habitat and refuge for a variety of species in streams. However, the flow features generated by submerged patches of vegetation can also pose a challenge for fish larvae. We conducted a series of experiments with live grass carp larvae (starting ∼50 h post hatch) in a laboratory racetrack flume, using a submerged array of rigid cylinders to mimic vegetation...

Invasive black carp as a reservoir host for the freshwater mollusk parasite Aspidogaster conchicola: Further evidence of mollusk consumption and implications for parasite dispersal Invasive black carp as a reservoir host for the freshwater mollusk parasite Aspidogaster conchicola: Further evidence of mollusk consumption and implications for parasite dispersal
Black Carp (Mylopharyngodon piceus) has invaded the Mississippi River and is a potential threat to native mollusks. During prior diet research, we discovered that the fluke Aspidogaster conchicola, a mollusk parasite, occurs regularly in the gastrointestinal tract of Black Carp. The fluke remains in fish intestines for extended periods after the fish has consumed its host. Flukes were...
